Well I first proposed this draft on the Foundation wiki and I was told that the premise and tone was better suited for the Library. Personally I agree.
The basic idea is a series of a slice-of-life tales involving a guy who is introduced by his girlfriend to the world of the occult. It will eventually, if it is a success, involve several GoIs, cameos of Foundationverse characters and objects. To sum up, it would be my attempt to put toghether my headcannon in a hopefully enjoyable way.
